PHILADELPHIA — Two more retired Philadelphia School District administrators have surrendered their credentials after an investigation into cheating on state standardized tests.

The Philadelphia Inquirer reports (http://bit.ly/1JCkwud ) 54-year-old Darlynn Gray and 45-year-old Ellen Berson turned in their certifications in the face of allegations that they violated the "integrity and security" of the Pennsylvania System of School Assessment exams.

The state didn't provide details of the misconduct.

Gray, a former principal, said Thursday she did the best she could do and there are "consequences for actions." Berson, who was an assistant principal under Gray, couldn't be reached for comment.

Both women retired in 2013.

They are the 10th and 11th district educators to be disciplined since a statewide cheating scandal was uncovered in 2011. Seven teachers and administrators have also been charged criminally.
